DOOR AND HINGE.

To all whom it may concern:

Be it known that I, JOHN MCMULLEN, a citizen of the United States,residing at Kent,

' in the county of Portage and State of Ohio,

have invented new and useful Improve.

ments in Doors and Hinges, of which the following is a specification.

This invention relates to-impro-vementsin doors and hinges and theprimary object thereof is to so construct a door and hinge that therewill be nofispace intervening between the rear edge of the door. whenopen and the portion of the door jamb which constitutes the abutment forthe door, into which careless or inexperienced persons might get theirfingers caught and injured by the sudden or unexpected closing thereof.

This invention is particularly adapted for use on doors of railroadcoaches, although equally applicable for other places. The ordinarydoors employed upon railroad coaches are hung upon common hinges andconsequently when opened a wide space intervenes between the rear faceof the door and the rabbet in the door jamb into which the same seats.These doors are customarily maintained in an open position by means of acatch placed on the floor of a car. Experience has shown that thecatches used for maintaining the door in open .position arefrequentlyinoperative, or the door is not opened far enough to cause them toproperly engage the same and passengers, more especially very carelessor inexperienced ones, entering or leaving the coach, frequently resttheir hands on the door j'amb for support and in so doing the fingersoften enter the rabbet into which the dodr seats and it is a veryordinary occurrence to. have the door suddenly closed by the stoppage ofthe cars, usually resulting in such serious injury to the ends of thefingers of the passengers as to require amputation; hence, b employingsuch a device .as is herein descri ed, such injuries to passengers areabsolutely prevented'and' the danger connected with the use of. a doorentirely eliminated.

A practical embodiment of my' invention is illustrated in theaccompanying drawings, in which, similar reference numerals indicatelike parts in the different figures.

In the drawings, Figure 1 is a perspective view of a door and jamb insection at a line drawn across the top of one of'the hinges of the door;Fig. 2 is a view of one member of the hingeyFig. 3 is the opposite orcooperat- Specification of Letters Patent.

ing member of the hinge; and, Fig. 4 is a perspective view of myimproved hinge complete. Y In the drawings, the reference numeral 1indicates a door jamb such as is commonly employed upon railroadcoaches, provided Patented. Dec. 24, 1907.

with the usual rabbeted portion 2 into which a the rear edge of the door15 seats. In order to make the door so that it will absolutely close therabbet ed portion ,2 and prevent any opening into which careless orinexperienced persons might get their fingers caught, the rear end ofthe door, designated by the reference numeral 3, is made semi-circularas shown in Fig. 1. The hinge which I preferably employ in connectionwith this form of door is so constructed as to be readily ap plied tothe ordinary door and jamb without materially altering the shapethereof, so that it can be readily applied'to those doors now in commonuse upon railroad coaches and consists of a member 4 comprising a plateprovided-with o enings 5 through which may be passed hold ast devices,such as screws, for maintaining it in a-properly positioned recess inthe rabbet 2.

Preferably integral with the member 4 is a laterally-projecting ear 6provided centrally with an opening 7. the hinge which is adapted to bepositioned in a suitably-formed recess inthe rear and side face of thedoor consists of a member 8 having a curvilinear configuration at oneend,

designated by the reference numeral 9, to correspond to the outersurface of the semi- The other member ofcircular portion of the door.This member 8 is provlded a proximately centrally with a pair of inwarly-extending ears 10 s aced apart and both provided with centraregistering perforations '11 through which may 4 .be passed a in 12constituting a' pivot for the hinge. he member 8 is also provided withopenings 13 through which may be passed holdfast devices, such asscrews, for

appropriate recess in the door. and 10 extend inwardly sufficiently so.that the perforations 7 and 11 are'in alinem'ent' effectuallymaintaining the member 8 in its The ears 6 the outer face thereof incontacting relation or approximately so with both the bottom of therabbet 2 and the inner angle 14 thereof, so that no matter in whatposition the door narily constructed, the majority of car doors are onlyadapted to swing a quarter of a revolution, so .that the o ening betweenthe edges of the rabbet 2 and the rearcnrvilinear face of the door willbe constantly in contacting relation to prevent the occurrence of anyopening between them, whether. the

door is open or closed. 7

Having thus described my invention, what I claim and desire to secure byLetters Patout, is 1. The combination with a rabbeted door frame, of ahinge member provided with a laterally-extending perforated portion, the

perforation being in alinement with the edge formed by the intersectionof said rabbet with one side of said frame and also equidistant fromboth of the side edges of said rab bet, a door provided with a convexedge, the axis of curvature of which is a proximately coincident withthe axis of revo ution of said door, a hinge member carried by said doorprovided with an extended portion. lapping the laterally-extendingportion of the other member, rovided with an opening registering withthe opening in the opposite member, the convex portion of said doorbeing of such a thickness as to approximately-constantly contact withone. of the side edges of said rabbet whereby no 0 en space existsbetween said rabbet an said door when said door is open.

2. The combination with a door; frame provided with a rabbet and a doorpositioned therein provided with a convex rear edge, a hinge membermounted in' said rabbet, a hinge member carried by said door, saidmembers being provided with lapping portions having registeringopenings, a pintle constituting an axis for said door, the position ofsaid pintle being in alinement with the edge formed by the intersectionof said rabbet with one side of said frame and equidistant from bothside faces of said rabbet, the convex side of said door extending intosai rabbet and arranged to constantly con-' tac with one face thereofwhen said door is moved.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN MQMULLEN.
